For more than half a century, Indian architect Charles Correa championed modern architecture, planning cities and designing nearly 100 buildings in the country, from luxury condominiums to housing for the poor.

Mr. Correa died Tuesday night in Mumbai, according to his son-in-law Rahul Mehrotra. He was 84 years old.

Among those who offered condolences was Indian Prime Minister Narendra Modi.

My deepest condolences on the passing away of the noted architect, Mr. Charles Correa. May his soul rest in peace: PM @narendramodi

Dubbed “India’s Greatest Architect” by the Royal Institute of British Architects in 2013, Mr. Correa worked on the master plan for Navi Mumbai, a satellite town of the western Indian city of Mumbai, in the 1960s. The town spread across an area of almost 133 square miles.

He was also involved in several low-income housing projects, like one in Belapur in Navi Mumbai, where he aimed to bring individual identities to tightly-packed housing units and, at the same time, ensure equity between the houses.

He also designed the “Gandhi Samarak Sanghralaya,” a memorial museum and research center at the Sabarmati Ashram in Ahmedabad, Gujarat. His design included areas that provided what Mr. Correa called “visual quiet.”

His love for unobstructed spaces seeped into a lot of his projects, like the luxury Kanchanjunga Apartments built over more than a decade in the 1970s and 80s in Mumbai where he incorporated the concept of “open-to-sky” spaces. He said that being able to see the sky from inside a building “can make a difference between livable habitat and claustrophobia.”

Some of his other projects include the British Council headquarters and the National Crafts Museum in New Delhi. In 2006, he was conferred with the Padma Vibhushan, the country’s second-highest civilian award.

Born in 1930 in the southern Indian city of Secunderabad, Mr. Correa studied at St. Xavier’s College in Mumbai and then went on to attend theUniversity of Michigan and the Massachusetts Institute of Technology in the U.S. to study architecture.

“To work in India is the great advantage of life in the Third World. The issues are so much bigger than you are; they give you a chance to grow,” Mr. Correa wrote in his book ‘Housing and Urbanization.’
